## Abstract Electron capture by and the subsequent fragmentation of a series of eleven fluorinated ฮฒโ€diketones of general formula CF~3~COCH~2~COR has been studied in an MSโ€50 mass spectrometer. Consecutive loss of two HF molecules from molecular anions occurs with all compounds, as does elimination

## Abstract The fragmentation behaviour of a series of six avermectins and two of their derivatives has been studied in the negativeโ€ion mode in the presence of ammonia. In contrast with positiveโ€ion mass spectra the negativeโ€ion spectra show abundant ions in the high mass region. Molecular mass de
